In the paper one presented studies concerning
renovation of the monumental building with strongly
moist brickwork. In order to determine moisture contents
in the masonry one used a quick and efficient method,
which consisted in measurements of relative air humidity
in the special openings drilled in the wall and next,
on that basis, in estimation of humidity of material
with use of the proper sorption isotherms for brick.
The presented approach can be used easily in a building
engineering practice
